Ecuador has mandatory electronic invoicing for all taxpayers, including non-residents meeting specific thresholds. Businesses must generate XML invoices, obtain authorization from the Internal Revenue Service (SRI) and use a digital signature for authenticity. E-invoices should be sent to the SRI within 24 hours, and taxpayers must store both the XML file and SRI acceptance message.


Fonoa offers a complete solution with plug-and-play capabilities for global e-invoicing requirements, including those in Ecuador. Our innovative platform ensures seamless implementation and easy compliance with tax regulations globally. We provide excellent customer service with support at every step of the process. Our unified API enables quick implementation, and we can offer assistance in just a few weeks.

What does
Fonoa offer?

  • Handle sequence numbering

    The sequence number is one of nine inputs used to generate the Unique Access key (clave), that SRI will use to authorize the document. Regarding serial numbers, this regulation states that these 9 digits must be completed i.e. 999999999 before starting a new one 000000001.

    This number is to be unique per issuer (i.e RUC, Branch, POS) and document type. So Credit notes, Invoices etc have their own sequences.

    Fonoa will handle the sequential number generation and automatically generate the Unique access code “Clave de acceso única” for each document. To do so we use the method called “Module 11”, with a weighted check factor; this error detection mechanism will be verified at the time of receipt of the invoice.

  • Unique Access key (Clave de acceso única)

    Fonoa automatically generates a unique access key of 49 numerical digits. This key is automatically generated by Fonoa and serves as the document's unique identifier and authorization number. Based on this key, the SRI will generate the response authorizing or not the invoice or electronic document sent by the taxpayer.

  • Generate a printed representation (RIDE)

    The current regulations for electronic invoices in Ecuador require specific provisions for the printed representation of electronic receipts (RIDE). This representation must contain a barcode adhering to the GS1-128 international standards and comply with the format specified in annexes 2 and 7 of the technical data sheet of the user manual. Also, Fonoa uses a suggested format for the physical representation of electronic invoices. See below how your invoices can look.

    When it comes to formal PDF content requirements, Fonoa enables a PDF generation within its standard global template, which incorporates details such as the issuer's RUC, full names and addresses, VAT amounts, and rates, among others. The design and layout of the physical representation of electronic invoices complies with all requirements in Ecuador, while we also offer customization of the template to meet unique business needs, such as using your own colors, fonts and logos.
